GOP Senators voted to "rebuke" the Massachusetts Senator, prompting her to read a letter from Coretta Scott King aloud on Facebook Live.

#LetLizSpeak was a trending on Twitter Tuesday night and into Wednesday morning after Senate Republicans voted to strike down the words of Sen. Elizabeth Warren’s (D-Mass.) against the Attorney General nomination of fellow senator Jeff Sessions (R-Ala.) saying her word’s impugned his character.

“The senator has impugned the motives and conduct of our colleague from Alabama,” McConnell said, then setting up a series of roll-call votes on Warren’s conduct. The vote went 47-43, strictly on party lines, and resulted in Warren not being able to speak during the remainder of the debate over Sessions.

McConnell specifically cited portions of a letter that King wrote to the Senate Judiciary Committee in opposition to Sessions’s 1986 nomination to be a federal judge.

King’s scathing 10-page letter read in part, “Anyone who has used the power of his office as United States Attorney to intimidate and chill the free exercise of the ballot by citizens should not be elevated to our courts.” (emphasis hers).

Sessions was later denied a federal judgeship.

Senators allege that Warren violated Rule 19 of the Senate that says senators are not allowed to “directly or indirectly, by any form of words impute to another Senator or to other Senators any conduct or motive unworthy or unbecoming a Senator.”

“I am surprised that the words of Coretta Scott King are not suitable for debate in the United States Senate,” Warren said after McConnell’s motion.
